King Yorick V Yronwood was supported in Nymeria's War by his bannermen, Houses Blackmont, Jordayne, Qorgyle, and Wyl, among many others. In the ninth year of warfare Mors died at Yorick's sword in the Third Battle of the Boneway. Nymeria took control of the Martell armies, however, and it took another two years of fighting before Yorick bent the knee and was sent to the Wall.[10] The Yronwoods became the most powerful bannermen of House Nymeros Martell of Sunspear, rulers of a newly-united principality.[11] The Yronwoods also have a rivalry with House Fowler, who supported the Martells in Nymeria's War.[1]

When Prince Oberyn Martell was sixteen years old, he was found abed with old Lord Edgar Yronwood's paramour. Although the ensuing duel was only to first blood, Edgar's wounds festered and he died shortly afterwards, originating rumors that the prince's blade had been poisoned and earning him the nickname of the "Red Viper". Oberyn fled to the Free Cities in exile. To "repay a blood debt", Doran Martell, Prince of Dorne, later sent his second child, Quentyn Martell, to foster with Edgar's grandson, Lord Anders Yronwood.[9] Quentyn served at Yronwood as page and squire, and he chose to be knighted by Anders instead of his uncle, Oberyn.[15] Quentyn was smitten with Ynys Yronwood, but the girl instead married Ser Ryon Allyrion. Her younger sister, Gwyneth, is interested in the prince.[4]

The Yornwoods are proud of their historical domains and power,[16] and the lord of the family is still referred to as the Bloodroyal.[17]
